MACHINE FOR REPAIRING ROADS.. i i

.. Specification of Letters Patent No., Y12,352, dated February 6, 1855.l l

To all whom t may concern:

Beit known that I, ALPHEsKIMBALL, of Fitchburg, in the co-unty ofWorcester and State of Massachusetts, have made certain new and usefulImprovements in Machines for Repairing Roads, of which the following isa full, clear, and exact description, reference being had to theannexedv drawings, making part of t-his specification, in which Figure lis a perspect-ive view of the machine the forward axle and wheels beingremo-ved; Fig. 2 a plan; Fig. 3 a section upon the line A, A, of Fig. 2;Figs. 4t and 5 details which will be referred to hereafter.

The principal part of my invention con' sists of a plow and a peculiarlyformed scraper, so combined with each other that while the formerloosens and raises the earth or gravel at the side of the road orin thegutter, the scraper which is peculiarly formed for the purpose,equalizes it and distributes it over the road, filling the ruts andforming the road way of the required height.

My invention also consists in certain improvements in the details of themachine which will be hereafter particularly set forth. =4 Toenableothers skilled in the art to make and use my road mender I willproceed to describe its construction and operation.

In the accompanying drawings B is the frame work of the machine, fro-mwhich the plow and road scraper are suspended, and to which the frontand back axles C, D', are pivoted as seen in the drawings.

E is o-ne of the cross timbers of the frame, to the end of which ismortised the vertical post F; to the bottom of this post is pivoted ata, the sole and land side piece Z). The forward end of the sole whichcarries the point G is suspended from the lever H by means of the postI, hinge K, and pivot (Z.

L is a cross timber secured to the framework at e, f, and carrying thepost M,` to which the lever H is pivoted at g. The lever I-I is guidedat its opposite extremity by a slotted post N, which is mortised to theframework B. The plow-point may thus be raised or lowered as required,by means of the lever H.

O is the mold board attached rigidly to the sole and point G, and risingand falling with them. The mold board is` pivoted at its rear end to thepiece P at the point l;

thescrew m and is madeadjustable for the purpose of raising or loweringthe mold board by means of the slot n. The mold board is made` of asufficient length to reach half way across the road, to its bottomsurface is secured the serrated scraper Q, which is curved to conform tothe cross section of the road. In hard and gravelly soils the resistanceupon the point of the plow would tend to swivel the who-le machine outof the direct line of motion;4 to counteract this tendency the forwardaxle C is pivoted to the frame at p near to its extreme end as seen inFigs. 1 and 2. In order still further to regulate the motion of themachine the hind axle D is pivoted to the frame-work at g, by whichmeans the axle may be secured in various positions either perpendicularor oblique to the line of motion, and thus ya this piece is secured tothe frame-work by l tendency is produced to carry the rear of the 'jmachine to one side or the other, as may be required to counteract theeffect of any ex- -axle is to be governed Aby the nature of the groundand the relative resistance offered to the plow point and scraper.

I will now describe the peculiar plow point which I make use of, andwhich is so constructed as to be capable of being turned over whendulledupon one side. In F ig. 5 is seen this point detached, the loweredge working in a horizontal plane and forming a continuation of thesole. By continued use the point will become worn as indicated by thered line in Fig. 5; when this takes place the point may be turned over,the surface t being placed at the bottom and the new point u being inthe plane of the sole as required, this point is thus self sharp-- eningand when dull requires but to be turned over to operate as at first.

It will be observed that this machine is capable of operating entirelyupon one side of the team and of the frame work and wheels, which isvery essential in a machine designed to be used for the purpose ofrepairing roads, as it is the material at the sides of the road near thefences7 and in the ditches that is required to be raised with the plowand distributed over the road way.

In order that the frame of the machine may run level, the wheels R and Supon the land side are made larger than the other two T, V, the latterrunning upon higher ground than the former. When the machine is operatedupon level ground the wheel R,

runs in the last furrow and the rea-r wheel S runs immediately behindthe sole in the furrow just formed.

What I claim as my invention and desire to secure by Letters Patent isl. The within described machine for Inaking and repairing roads,consisting essentially of the combination of the plow and scraperconstructed in the manner set forth and suspended from the lever HQ 2. Iclaim pivoting the rear aXle and Securing it to the frame work in aposition oblique to the `direction of motion` for Jche purposedescribed.
